SPECIFICATION forming part of Letters Patent No. 621,485, dated March21, 1899.

` Application filed February '7, 1899.

T0 all whom-t may 0077/067171,.-

Beit known that I, KNUT BULAND, a citizen of the United States, residingat Linn Grove, in the county of Buena Vista and' State of Iowa, haveinvented a new and usefulv Thill- Coupling, of which the following is aspecification. y

This invention relates to thill-couplings; and the object thereof is toprovide improved means whereby the bolt may be tightly held againstrattling and also permit of the same being removed to substitute a polefor the thills, or vice versa.

To these ends the present invention consists in the combination andarrangement of parts, as will be hereinafter more fullydescribed, shownin the accompanying drawings, and particularly pointed out in the ap'-pended claims.

In the drawings, Figure 1 is a perspective View of the device. Fig. 2 isa transverse sectional View thereof. Fig. 3 is a detail perspective viewof the bolt.'

Like numerals of reference denote like and corresponding parts in eachof the several figures of the drawings.

Referring to the accompanying drawings, 1 designates an axle-clip iittedto an axle 2 in the ordinary manner and provided with spaced ears 3.Each of the ears is providedv with a slot 4, open at the top thereof,and the slots are alined transversely across the ears.Outwardly-extending flanges 5 are provided at opposite sides of eachslot, Hush with the upper faces of the ears and inclined or beveledinwardly and downwardly, vas at 6, from the outer edges of the ianges tothe sides of the ears.

As illustrated in Fig. 3, the coupling-bolt has at one end a fixedtransverse head 8,which is beveled, as at 9, upon its upper and lowerfaces convergently from the outer side toward the bolt. .A loose oblongwasher 10 is slid# ably fitted upon the other end of the bolt and isprovided with beveled upper and lower faces 11, which are disposedoppositelyj to those of the head 8. A suitable nut 12 is provided uponthe bolt outside of the washer.

To assemble the coupling, the nut and washer are removed from the bolt,and the latter is placed in the eye of the thill-iron 13. The bolt isthen fitted in the slots 4 of the Serial No. 704,813. (No model.)

ears 3, through the upper open end thereof, and then the washer and nutare iitted to the end of the bolt, which projects beyond one of theears. the slots of the ears, the head 8 and washer 10 are below theflanges 5, and by tightening up on the nut the beveled faces of the headand Washer are drawn tightly against the beveled faces of the respectiveiianges 5 and a binding iit is had therebetween. gagement of the washerand head with the .flanges of the ears prevents the bolt from beingjolted upward, and the fixed head prevents the bolt from turning in theslots. To guard against the nut from being accidentally loosened by themovement of the vehicle and the thills, a suitable key 14 is fittedthrough the-outer end of the bolt against the nut. Y

The present construction and arrangement provide but few parts, all ofwhich are positively and substantially connected together, wherebyrattling of the bolt and loss of any of the parts are prevented and thethills may be readily removed when desired.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacrif ficing any of the advantagesof this invention.

Having thus described the invention, what I claim isj 1.Athill-coupling, comprising an axle-clip having opposite spaced earswhich are provided with alined slots and outwardly-extending flanges,and a coupling-bolt having a fixed head at one end, a washer slidableupon the other end of the bolt, and means for adjusting the washerthereon, the bolt being adapted to be fitted in the eye of a thill-ironand in the slots of the ears, whereby the head and When the bolt isAthus seated in The enthe washer may be engaged with the flanges of theears and retain the bolt in place, substantially'as shown 'anddescribed.

2. A thill-coupling,comprisin g an axle-clip having opposite spacedears, each ear having an outwardly-extending beveled or undercut iiange,and a transverse vertical slot formed therein, and a bolt having a fixedbeveled head, a beveled washer slidable upon the bolt, and a nut foradjusting the washer, the bolt being adapted to be fitted in the eye ofthe thill-iron, and in the slots of the ears,wl1ere by the beveled facesof the head and washer may be engaged with the respective beveledflanges ot' the ears, substantially as and for the purpose set forth.

3. In a thill-coupling, the combination of an axle-clip having oppositespaced ears, each ear being provided with a vertical transverse slotopen at its upper end, and outwardly-extending flanges flush with theupper face of the ear, undercut or beveled inwardly and downwardly anddisposed at opposite sides of the slot, and a coupling-bolt having afixed transverse head convergently beveled toward the bolt upon itsupper and lower faces, an oblong washer slidably 'fitted upon the bolthaving its upper and lower faces beveled op- KNUT BULAND.
